Does anyone know about axis-symmetric topology optimization?

In summary, ABAQUS offers geometric restrictions like planar, rotational, and other symmetries, but not axis symmetric. While a 2D axis symmetric element model can be created in the PART section, the possibility of optimizing a full 3D element model with axis symmetry is unclear. Load and boundary conditions can be applied to a specific zone, but it is uncertain if this can be achieved using software or methodology. CAD is commonly used to make parts, and software such as Polyworks can be used with manual coordinate measurement ARM to measure size, shape, and surface texture parameters. Various parameters like flatness, squareness, out-of-roundness, and concentricity can be scrutinized using this software.

ABAQUS provides geometric restrictions such as a planer, rotational, and other symmetric,
but there is no axis symmetric restriction.
I know that the 2D axis symmetric element model could be possible to make in PART section.
But I want to know that a full 3D element model could be optimized by axis symmetric, because the load and boundary condition is applied in a specific zone like the figure below. (If the load is applied 2D model, it will apply to all elements of the same orbit location.
Is there a software or methodology that this can be implemented?

I assume you are using CAD to make the part. I have sold machines to MEASURE parts produced for size, shape and surface texture parameters. A popular software used with a manual coordinate measurement ARM is Polyworks. After you paint the part with a laser, various parameters may be scrutinized. Flatness squareness size out-of - roundness, diameter, concentricity etc. There are many softwares available for this.
 

FAQ: Does anyone know about axis-symmetric topology optimization?

What is axis-symmetric topology optimization?

Axis-symmetric topology optimization is a method used in engineering and design to find the optimal shape and distribution of material in a structure that is symmetric around an axis. This method helps to reduce the weight and improve the performance of the structure.

How does axis-symmetric topology optimization work?

Axis-symmetric topology optimization uses mathematical algorithms to determine the optimal shape and distribution of material in a structure. These algorithms consider factors such as stress, strain, and displacement to find the most efficient design for the given parameters.

What are the benefits of using axis-symmetric topology optimization?

Some benefits of using axis-symmetric topology optimization include reduced weight, improved structural performance, and cost savings. This method can also help to identify potential design flaws and improve the overall efficiency of the structure.

What types of structures can benefit from axis-symmetric topology optimization?

Axis-symmetric topology optimization can be applied to a wide range of structures, including mechanical components, aerospace structures, and even biological structures. Any structure that is symmetric around an axis can potentially benefit from this optimization method.

Are there any limitations to axis-symmetric topology optimization?

While axis-symmetric topology optimization can be a powerful tool, it does have some limitations. This method may not be suitable for structures with complex geometries or non-symmetric loading conditions. It also requires accurate input parameters and may not always provide a feasible design solution.
